GAS-IGNITING APPLIANCE.

SPEGIFICATION forming part of Letters Patent No. 760,937, dated May 24,1904.

' Application filed September 21, 1903. Serial No. 173,994. (No model.)

To all whom it may concern:

Be it known that we, DOUGLAS TAYLOR and WALTER MARTIN TAYLOR, residentsof the city of Toronto, in the county of York and Province of Ontario,Canada, have jointly invented certain new and useful Improvements inGas-Igniting Appliances; and we hereby declare that the following is afull, clear, and exact description of the same.

This invention relates to a gas-igniter for that class of gas-burningappliances in which the gas-burners are arranged in a cluster or groupand provided with a continuously-burning gas-igniting flame opposed toone of the burners or located between two adjacent burners to ignite thegas as it issues from them when the cut-off valve has been actuated toopen the gas-supply to the cluster or group. In this class ofgas-igniting appliances the remaining burners of the cluster or groupdepend for'ignition upon the explosion caused by the outflowing gascoming into contact with the flame of the primarily-ignited burner orburners, such explosions not only producing unpleasant reports ofgreater or lesser degrees of loudness, but also frequently causingconsiderable damage, particularly by shattering the globes and theincandescent mantles with which the burners'may be fitted. To obviatethese explosions when igniting the burner cluster or group is the objectof the present invention, which is accomplished by employing an ignitingappliance having flameapertures opposed to all the burner-tips and aflame-slot forming a means of communication between the flame-aperturesto enable the ignition of the gas at any part of the igniting applianceto instantaneously ignite the gas at all of the flame-apertures andmaintain an igniting-flame opposite each burner to ignite the gas as itreaches the burner-tips'when the cut-off valve has been actuated toadmit the gas to the burner cluster or group.

The invention may be carried into practice by connecting the burners toa common burner base or head fitted with a cut-off valve between itsinlet and outlet ports and providing the burner cluster or group with acluster-igniter located in juxtaposition to the burner-tips andconnected with the burner- 5 burner-base between the cut-off valve andthe inlet-port being fitted with a tube extending to the cluster-igniterto maintain a continuous flame to instantaneously ignite the gas as itissues from the cluster-igniter.

The cluster-igniter instead of being con- -nected to the burner-basebetween the cut-off valve and the outlet-ports may be connected to theburner-base between the inlet-port and the cut-off valve, or it may beconnected to the gas-supply pipe at any convenient point. In 5 all ofthese cases it is necessary to provide the cluster-igniter with its owncut-off valve and open it in advance of the cut-0E valve for theburner-base, so that the cluster-igniter will become charged with gasand ignited by the 7 continuous flame to prepare for the ignition of thegas as it reaches the burner-tips when the burner cluster or group hasbeen charged by the opening of the cutoff valve controlling the supplyfrom the gas source to the burners,

the cut-01f valve of the cluster-igniter being closed to extinguish theigniter-flames when the gas issuing from all of the burner-tips of thecluster or group is ignited. v

For an understanding of the invention we have hereinafter described andhave shown in the accompanying drawings the means above referred to ofcarrying the foregoing object into practice; but as it is possible toattain the same results by several other modi- 5 fications of acluster-igniter arranged in the same relative position to theburner-tips we do not wish the invention to be confined to, the specificmeans described and shown.

In the drawings, Figure .1 is a perspective 9 view of a burner clusteror group fitted with incandescent mantles, showing the cluster-ignitingappliance. Fig. 2 is a similar view of a modification of thecluster-igniting appliance. Fig. 3 is a perspective view of thecluster-igniter. Fig. 4 is a view of the tube for the cluster-igniter.Fig. 5 is a sectional view of the cluster-igniter and tube. Fig. 6 is aperspective view of a second modification, and

Fig. 7 is a sectional view of the cut-off valve. Like letters ofreference refer to like parts throughout the specification and drawings.

Connected to a pendent gas-pipe a is a burnerbase Z), consisting of avalve body or casing having at its lower end horizontal arms 0,fittedwith adjustable valves (Z to regulate the volume of gas passing to theburners a. As shown in Figs. 1 and 2 of the drawings, the burners e areconnected to the horizonal arms cand are grouped or clustered around thevalve body or casing 5 to occupy as small a space as possible; but theymay, if so desired, be arranged in a straight row, as shown in Fig. 6,and formed in the lower ends of the burners e are apertures I throughwhich air is admitted to mix with the gas as it passes to theburner-tips Z.

Within the valve body or casing b is the cutoff valve m, located betweenthe inlet-port m and the outlet-ports 0' to control the flow of gas fromthe gas-supply source to the gasburners, and connected to the valve bodyor casing?) between the cut-off valve m and the gas-pipe a is a gas-tube0, the tip of which is in sulbstantially the same plane as the burnertips ter-igniterp, which in the construction shown in Fig. 1 isconnected with the valve body or casing 6 between the cut-off valve mand the outlet-port 0 by a gas-tube q, through which the gas may pass tothe cluster-igniter when the cut-off valve on is being opened to allowof the gas passing from the gas-pipe a to the gas-burners e. In thecluster-igniter p are a series of flame-apertures 9', opposed to theburner-tips Z, and connecting the flame-apertures 1" is a diminutiveflame-slot 8, through which a small leakage may occur when thecluster-igniter is charged with gas. A continuous flame is maintained atthe tip of the gas-tube 0 by the constant flow of gas from the gas-pipeto ignite the gas as it issues from the cluster-igniter at a pointopposite the tip of the gas-tube 0. The gas ignited at this pointtravels instantaneously, by means of the diminutive slot, to all of theflame-apertures a, which, being opposed to the tips of thegasburners,cause the simultaneous ignition of the gas at the burner-tipsimmediately after the opening of the cut-off valve of the cluster orgroup.

In the construction shown in Figs. 1 and 6 the cut-off valvem is soarranged in the valve casing or body that it will open the gas-supply tothe cluster-igniter to permit of its ignition before fully opening thepassage to the gas-burners, so that the cluster-igniter caninstantaneously ignite the gas as it issuesfrom the burner-tips. Asshown in Fig. 2, it is possible to connect the gas-tube q with thegas-pipe a and fit it with the cut-off valve t, which may be opened inadvance'of the opening of the cut-off valve m to allow of the clus-Opposed to the burner-tips Z is a cluster-igniter being ignited inadvance of the charging of the burners and which may be closed to cutoff. the supply of gas to the cluster-igniter when all the burners ofthe cluster orgroup have been ignited to economize as far as possiblethe use of the gas by prevent-- ing its unnecessary consumption by theeluster-igniter. Projecting upwardly from each burner-tip Z is amantle-supporter u, and suspended from each mantle-supporter a is anincandescent mantle 'u.

Heretofore the means provided to ignite the gas-burners was a continuousflame at the tip of the gas-tube 0, which was opposed to one of thegas-burners or located between two adjacent burners, so that when thecutoff valve had been actuated to charge the gasbnrners the continuousflame ignited the gas issuing from the burner or burners adjacent to it,the remaining burners of the group or cluster depending upon the'globebeing filled with gas and ignited by the ignited burner or burners, theignition of which caused an explosion of the gas and often resulted inthe shattering of the incandescent mantles and occasionally in thebreaking of the globe.
